High Quality Content by WIKIPEDIA articles! The Berlin Stadtbahn ("city railway") is a major railway thoroughfare in the German capital Berlin, which runs through Berlin from east to west. It connects the eastern district of Friedrichshain with Charlottenburg in the west via 11 intermediate stations including Hauptbahnhof. The Berlin Stadtbahn is often also defined as the slightly longer route between Ostkreuz and Westkreuz, although this is not technically correct.
